.To aZZ whom it may concern:

Be it known that we, FREDRIOH DOM- BROWSKI and JACOB WOLTMANN, of St. Louis, Missouri, have jointly made a new and useful 5 Improvement in Shoe-Lasting Machines, of which the following is a full, clear, and exact description.

. The improvement relates more especially to the construction of the jack; to the means for drawing the upper onto the last, and for closing it over upon the insole; to the means for adjusting the last to the movement of .the gripping device as the upper is closed upon the insole; to the means for holding the upper in :5 place after it has been drawn onto the last and closed upon the insole, and to the means for applying-the upper to'the insole.

specification, exhibit the improved construc- 20 tion.

Figure 1 is a side elevation of the machine. Fig. 2 is a front-elevation of the machine. Fig. 3 is a horizontal section onthe line 3 3 of Fig. 1. Fig. 4 is a horizontal section on the line Fig. 5 is a view in perspective of one of the grippers, being the one used at the toe of the shoe. Fig. 6 is ahorizontal section on the line 6.6 of Fig. l. Fig. 7 is asimilar section, the clamp being'opened. Fig. S 30 is a horizontal section on the line 8 8 of Fig. 1. Fig. 9 is a horizontal section on the line 9 9 of Fig. 1. Fig. 10 isa. side elevation showing the grippers applied to the upper. Figs. 11 and 12 are sectional views on the line 11 12 of Fig. 10, and respectively of a right and left shoe. Fig. 13 is a similar section, but showing the grippers closed toward each other and the upper edges drawn downward upon the insole. Figs. 14 and 15 are views corresponding, respectively, to Figs. 11 and 12, and showing the clamp bearing upon the upper edges. Fig. 16 shows the nail-holder resting upon the upper and supporting the nails in position for nailing. Figs. 17 and 18 are views illustrating the method of driving the nails. Fig. 19 shows the upper nailed to the insole. Figs. 20 and 21 are respectively a plan and a side elevation, partly in section, of the nail-holder; and Figs. 22 and 23 are respectively 'a plan punch used to introduce the nails.

The same letters of reference denote the same parts.

The last A, Figs. 1, 2, having the upper (not shown in the figures named) attached, is' placed in position upon the jack B and moved into position for the upper to be acted upon pybthe mechanism for stretching it upon the Thejaek consists, mainly, as follows: aheelsupport, I), a toe-support, b, a plate, 0, upon which the supportsb b are more immediately placed, asub-plate, b and guide-pins b,which extend from the plate b" downward throu h the sub-plate I), and a screw,-b, which sn pports the plate'b" and in turn is held and adapted to be workedupward and downward in a block. b that is held in the subl a The annexeddra'wings, making part of this p ate b The heel-support b is jointed at b to a hearing, b upon the plate b, and by means of the wedge I), which is pivoted at b" to the plate 11*, the heel-support can be turned upon its bearing toward and from the toe support, and

thereby adjust the last with relation to the toe-support and clamp and nnclamp the last, as may be desired. The toe-support can be ad usted upon theplate I)" toward and from the heel-support by means of the screw b", which is held in the standard 0 and works throughthe toe-su port. In this mannerprovision is made for ongeronshorterlasts. By means of the screw b the plate I) and the parts thereupon can be raised and lowered to a limited extent for the purpose of adjusting the last more accurately in a vertical direction. The pinsb guide the platebin'the movement last described. i

The jack as an entirety is adapted to'be moved toward and from the standard 0 by adapting the sub-plate bto be heldaud moved o in a'base-plate, D.

To receive the last the jack is drawn out upon the base-plate into the' position-shown 1n the full lines in Fig. 8, and after the last has been secured the jack-is slid inward upon 5 the base-plate into the position indicated by" I the dotted lines, Fig. 8, and the full lines in Fig. 1. The base-plate D is attached to some fixed part of the machine, such as the arm E which also supports the gripping mechanism and clamping mechanism, which will now he described. I

The mechanism for gripping the upper F, Figs. 10, 11, 12, anddrawing it upward upon the last and afterward closing its upper edge over upon the ins'ole, .G, consists, mainly,first, of the grippers H, Figs. 1, 2, 4', 5, which are adapted to lay hold of the upper; second, a head, h, to which the grippers are attached, and which is adapted to be raised and lowered in the arm E, and thereby to draw the grippers upward and lower them downward, as desired; and, third, a guide, I. which can be made to coact with thegrippers and cause them to be moved horizontally, and thereby "enalile'the edge of the upper to be'drawn over upon the insole. A series of tlie grippers H is employed in order that the upper may be taken holdof along the sides and at the toe of the last; The grippers are generally similar,

but' ina'y be varied slightly to accord with their respective positions around thelastthat is, they allhave sot e appliance, such as the jaw It, pivoted at h" o the main arnr h of th'ej gripper and adapted 'by in'eans of a spring,
